Installation.

=============

Run setup.exe. Use output dir like::

  d:\opt\cygwin

Add to your PATH env var exactly before C:\WINDOWS\system32;C:\WINDOWS values::

  set PATH=d:\opt\cygwin\bin;d:\opt\cygwin\usr\local\bin;%PATH%

  REM Set CYGWIN variable to 'nontsec'. That makes sure that permissions

  REM on your windows machine are not updated as a side effect of cygwin

  REM operations.

  set CYGWIN=binary nontsec nodosfilewarning codepage:cp1251 noglob

  set LANG=ru_RU.cp1251

Set HOME env var (where places config file and projects)::

  set HOME=d:\home

Set TMP and TEMP env vars with good path (without spaces, etc.; these vars

already set as used defined, so you need change their values)::

  set TMP=c:\tmp

  set TEMP=c:\tmp

Also you need edit /etc/passwd to point to correct home path.
